Hello /sci/
Can you please help me find the flowing pdfs:

1)E.C. Young, Partial Differential Equation
2)P.W. Berg and S.L. McGregor, Elementary Partial Differential Equations

Your help would be greatly appreciated
t. poor CE student

is there research being done into new analytical DE methods?

I need to learn difffential equations and linear algebra by September.

What is the best way of doing so?
>inb4 "Khan academy"
I'm not trying to hear about the "in-flect-shun point and this guy here cancels that guy"

Why is the study of differential equations important for pure mathematics?

I understand why DEs are important from a practical view in that they can be used to model many phenomena dealing with change, however why are they important in connection to other areas of mathematics?

Does /sci/ have any good resources on learning about PDEs and how to numerically solve them?

How does Partial Differential Equations compare to Ordinary Differential Equations?

I'm taking an introductory ODE class right now and it's honestly the most tedious and boring math class I've taken.

Mind you that I have about a 97% average in the class. It's all just about mechanics and solving silly ideal equations that youd likely never encounter in the real world. In addition it seems like a class completely tailored to the physicists and engineers, with nothing interesting in it for the math majors.

Also, after taking Calculus 1-3 and now ODEs, I'm getting a bit bored of the calculus series.

What areas should I explore next? I was thinking of taking courses in Abstract Algebra, Modern Geometry, or Combinatorics.

Do pure mathematicians actually use anything they learn in a typical differential equations course?

I don't see how any of these methods of solving DEs is applicable to higher mathematics.

I'm in need of some guidance, fellow mathematics majors.

I'll be done with Introduction to Abstract Math, Calculus 3, Differential Equations, and Linear Algebra by the beginning of the Fall 2015 semester.

After that, I can either take Modern Geometry or Intro to Partial Differential Equations.

I want to take the geometry class since it seems more imagination and fun (for lack of better words) and the PDE class seems geared towards physics and engineering majors (I'm a chemistry major).

Which one did you guys enjoy more?

Trying to find the general solution for this diff eq:

∂y/∂ x + 3y = 0

Is this a solution:

y=a(e^-3)

I'm going to star studying differential equations in two months, any good books you can recommend?
